This invention has reference to air wash ers for use in connection withexplosion engines where the atmosphere is liable to be charged, to adetrimental eXtent,with dust.

The object of vthe invention is to free the air entering the air intakeof the carbureter used in connection with an internal combustion enginefrom dust or other'impurities andto charge the cleansed airwi'th wateryvap r n a Warm c0ndi n,. Wa mth nd moisture contributing markedly to theefli ciencyo'f theengine. I-

V In accordance with the invention there is provided a casinghaving anair intake and an air outlet, the latter being arranged tobe connectedto the air ntake of the carbureter. The air intake is located at a'highpoint in he casing, and in the pat {o the stream of air enteringtheintakethere is a chamber containing a series'of staggered perforatedpartitions designed to conduct water and air so that-dust which mayoccur in the air stream is gathered up and directed to a body of watercontained in the casing and the w'ateris finally returned to the inletof the radiator, of the automobile, the return connection being locatedhigh enoughso that the portion of the casing below the level of thewater retifined to the'radiator constit t tutes a mud drum,- Water isconducted from the water jacket of the engine into'the 9 62 1 1" casingabove the perforated partitions so as to gravitate through alternateends of the partitions in order; Provision 1s; madefor F the occasionaldraining of the casing to remove accumulations of dust inthej formiof,niud. i I The invention will be best understood from a consideration ofthefo'llowingde tailed description taken in connection with theaccompanying drawings forming part of this specification, withthetunderstand ing, however, that the invention is not confined to anystrict conformity with the showing in the drawings, but maybe changedand by a e rrang d ther partitions 13. Within the" chamber above the-topmost partition 13 ,.modified solong as such changes andmodifications mark no material departure from the I salient features ofthe invention as expres%d v in the appended claims.

made iorfclrawin ou'tjaccurnulations from istobe associated. j v i Atadistant point in the chamber 1 from the outletpipe' 8 and sufficientlylow therein tobejsomewhat above the mud drum, is another outl'etpipe 9designed to be connect ed to the; intake portion of the radiator, of jthe' explnosion 'e ngineQ" In the upper portfo'n o-f' the 'casing lthere 1 c amb 'r 10,.form'edin most part'by th of the casing l, andhaving av parti- "tionfll extending across the casing. The partition '11and chamber 10ers upright like }tl'1e easing 1 while the bottom of thechamforined by a pa-rtition'l2 above which is ajpipe 1% extendingdiametrically across partition l2 and 13 is arranged substantiallyhorizontally and is providednear-one edge "f with apassage15therethrough and has perate= {forati'ons16or the like acent to the pasmay high point, in the as,

I i r;' intake of the carbu t r .lo'sion. re'll'l ne with which the airp w v theflower par-t of the casing-l, constitutingf v the lower portionof the casing l constitut sag-e15. Between the perforations 16 and theother edge of the partition the latter 1s imperforate.

The pipe 14 has perforations 17 therethrough for a portion of itscircumference and directed toward the imperforate part of the uppermostpartition 13. g

With the air washer properly installed tween the radiator and thecarbureter as shown in Figure 4'so that a stream of air may be'directedthrough the air washer, a stream or spray of hot water is directedthrough the perforations 17 on to the uppermostpartition 18, to flowover the perforations 16 in the partition, through which the water dropsto the imperforate part of the n'eztt underlyingpartition, to flowthrough I the perforated part thereof, and drop on to the imperforatepart, of the nest partition, and so on, the water finally passingthrough thellowe'rmost partition into the mud drum where the water levelmay approximate the level indicated by the dotted line 18.

The suction of the engine draws air through the head 2, into the chamber10 where the air is directed about'the pipe 14 and through streams ofwater issuing from the said pipe 14 by way of the perforations 17. TheWater readily takes up the particles of dust and asthe Water falls uponthe uppermost partition 13 it carries the dust "particles with it, sothat the air, on reaching the passage 15 in the uppermost partition 13,

is much cleaner than when it entered the casing 1. The a1r streamcontinues its course through the casing 1, through a path renderedtortuous bythe staggered relation of the groups of perforations 16 andthe passages 15. After passing through the lowermost partition 12 thewater falls to ing themud drum, for flow back to the inlet of theradiator through the outlet pipe '9, while the cleansed air passesthrough the outlet pipe 8 and from thence to the air in take of theengine carbureter.

. The result is that only thoroughly cleansed air reaches the carbureterand this air is warmed air since it has been: caused to traverse streamsof water previously heated in the water jacket of the engine. Theinvention has the advantage of contributing .to the vaporization of thefuel because of the pre-heating of the air mixed with the fuel in thecarbureter, while the effect on the radiator is to reduce thetemperature of the water entering the radiator, the passage of eliminatethe heat therefrom. These advantagesare in addition to the principaladvantage of the invention, which is to render it feasible to-use the,en *ine in atmospheres heavily charged with cust particles. 7

Such atmospheres are particularly liable to be met with in farmingoperations where the water through the partitionsserving to cylinders,pistons and valves of'the engine will be quickly and seriously harmed,re-

quiring frequent repairs and consequent heavy expense.

By means of the invention herein dis- I .closed, I am able to supplyclean, moist,

warm air'to the carbureter ofthe engine, and in return deliver to theradiatorcool water deprived of any dust, the'circulation of the waterbeing continuous and effected without a circulating pump. f

An air washer and charge humidifier a adaptable for connectionbetween theradi v delivering water therefrom, and acham her in thecasing'having perforated partitlons wlththe perforatlons lnthe severalpartitions in staggered relation, said cham-" ber vbeing located belowthe water inlet and above the water outlet pipe and spaced from the airoutlet pipe, whereby the air is caused to pass through streams of waterbefore it reaches the air outlet pipe on its way to the enginecarbureter.
